Description Alex Fiestas 2011-01-04 12:19:09 UTC 
If when I start my laptop the HDMI wire is not connected, xrandr reports a "DVI" interface, but if instead I start my laptop having the HDMI wire connected an HDMI interface is reported.

This seemed a painless issue to me until I discover that the sound is not streamed to the HDMI port when it is detected as DVI.

Seems that is not working, xrandr is still reporting "DVI1" as name instead of HDMI1, and sound is not being forwarded.

To test the patch I use linus+git://git.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel.git + the patch.
